ANTENNA.

Application filed November as, 1924. Serial No. 752,733.

The present invention relates to wireless communication utilizing anaerial for the interception of radio frequencies which are convertedinto audible signals and it is the purpose of the present invention toobtain better reception of the high frequency waves on a short aerial,and this is accomplished by the addition of capacityelements to theantenna wire.

Other objects and advantages will be apparent and suggest themselves asthe nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to beunderstood that in adapting the same to meet difierent conditions andrequirements, various changes in the form, proportion and minor detailsof construction may be resorted to without departing from thenature ofthe invention.

Referring to the accompanying drawings forming a part of thespecification,

Figure 1 is a top plan view of a length of antenna embodying theinvention,

Figure 2 is an edge view thereof,

Figure 3 is a plan view of a modification,

Figure 4 is a side view of the modification shown in Figure 3,

Figure 5 is a side view of a modified form of antenna consisting of awire provided with pendants each carrying a plurality or" capacityelements, and

Figure 6 is a sectional View taken on the plane indicated by the line6-6 of Figure 5, looking in the direction indicated by the arrows.

Corresponding and like parts are referred to inthe following descriptionand designated in the several views of the drawings by like referencecharacters.

Referring to Figures 1 and 2, the numeral 1 designates a metal ribbonwhich may be of any length and width, and which is provided at one endwith a snap hook as indicated most clearly at 3 in Figure 2. A pluralityof oapacityelements a are mounted upon the ribbon l and may be spacedapart any determinate distance as may be found most advantageous, andthese elements consist of cylinders of thin sheet metal having theirsides corrugated in a spiral or helical form substantially as indicated,said elements being mounted upon the metal ribbon and made fast theretoby means of screws 5.

In the modification, the numeral 6 denotes a short length of metalribbon having capacity elements 4 mounted thereon and projectingalternately from opposite sides as indicated most clearly in Figure 4:,said capacity elements being attached to the metal ribbon by means ofbolts 7 or analogous fastening means. One end of the metal ribbon 6 isformed into a roll 8 and the opposite end has an eye 9 applied thereto,and which is adapted to receive an antenna wire 10 upon which thecapacity element equipped strips or metal ribbons 6 are strung andequally spaced, as shown most clearly in Figure 5.

hat is claimed is 1. An aerial provided in its length with unitelements, said unit elements consisting of sheet metal cylinders havingtheir sides formed with spiral or helical corrugations.

2. An aerial comprising a ribbon having unit elements applied theretoand projecting from the sides thereof in various directions, saidelements consisting of sheet metal cylinders having their sides formedwith corru gations.

3. An antenna, elements loosely strung on the antenna and unit elementsprojecting laterally from the pendant elements strung upon the antenna,said elements consisting of sheetmetal cylinders.

4. An aerial consisting of an antenna wire, metal strips strung upon theantenna wire and maintained in determinate spaced relation, and unitelements carried by said strips and projecting laterally from oppositesicles thereof in alternation, said elements consisting of sheet metalcylinders.

5. An aerial comprising a ribbon antennae, unit elements generally oftubular
